It is too bad what you went through. A blood test does not mean your body had below normal levels of mercury. Mercury does not hang out in the blood. It resides mainly in the brain, then the organs and lymphatic system, then blood and urine. To accurately test mercury in your system, you need to get a fractionated porphyrin test (i recommend both fecal and urine) for mercury. I have seen people with 2 fillings that were very poisoned with mercury. If you have mercury fillings, you have mercury poisoning. To what degree and to how much it is affecting you is the question. Each person's immune system deals with it differently, although there are some commonalities in symptoms. But the fractionated porphyrins can measure it accurately in your body. you may want to post in debate: http://curezone.com/forums/f.asp?f=100629&t=26972
